Component Description

Master Window Control Switch

The master window control switch receives voltage whenever the interior light relay (located in the BCM (Body Control Module)) is active. The master window control switch is grounded through the DDM (Driver Door Module). The master window control switch communicates to the DDM (Driver Door Module) through a private LIN (Local Interconnect Network).

Passenger Window Control Switch - Front

The RH (Right Hand) front window control switch contains momentary contacts (one for each window switch direction). The PDM (Passenger Door Module) provides a return (ground) for the RH (Right Hand) front window control switch. When the control switch is activated, a ground signal is supplied to the PDM (Passenger Door Module) to operate the window motor in the desired direction.

Passenger Window Control Switch - Rear

Each of the rear window control switches contains momentary contacts (one for each window switch direction). The DRDM (Driver Rear Door Module) or PRDM (Passenger Rear Door Module) provides a return (ground) for the rear window control switch. When the control switch is activated, a ground signal is supplied to the DRDM (Driver Rear Door Module) or PRDM (Passenger Rear Door Module) to operate the window motor in the desired direction.

Window Regulator Motor

The window regulator motor(s) are bi-directional. Window direction is determined by the polarity of the voltage being supplied to the motor from the associated door module. The window regulator motor contains 2 Hall-effect sensors. The Hall-effect sensor power supply and return circuits are provided by the associated door module.

Front Display Interface Module (FDIM)

The FDIM (Front Display Interface Module) contains a redundant rear window defrost button on the touchscreen display. The FDIM (Front Display Interface Module) plugs directly into the APIM (Accessory Protocol Interface Module), and does not communicate directly on any network.

Driver Door Module (DDM)

The DDM (Driver Door Module) receives power window commands from the master window control switch through a private LIN (Local Interconnect Network). The DDM (Driver Door Module) supplies voltage and ground to operate the LH (Left Hand) front power window motor.
The DDM (Driver Door Module) also communicates master window control switch requests to the DRDM (Driver Rear Door Module) through a private LIN (Local Interconnect Network) and to the PDM (Passenger Door Module) through the MS-CAN (Medium Speed Controller Area Network).

Passenger Door Module (PDM)

The PDM (Passenger Door Module) receives power window commands from the RH (Right Hand) front window control switch or from the DDM (Driver Door Module) through the MS-CAN (Medium Speed Controller Area Network). The PDM (Passenger Door Module) supplies voltage and ground to operate the RH (Right Hand) front power window motor.
The PDM (Passenger Door Module) also communicates master window control switch requests to the PRDM (Passenger Rear Door Module) through a private LIN (Local Interconnect Network).

Driver Rear Door Module (DRDM)

The DRDM (Driver Rear Door Module) receives power window commands from the LH (Left Hand) rear window control switch or from the DDM (Driver Door Module) through a private LIN (Local Interconnect Network). The DRDM (Driver Rear Door Module) supplies voltage and ground to operate the LH (Left Hand) rear power window motor.

Passenger Rear Door Module (PRDM)

The PRDM (Passenger Rear Door Module) receives power window commands from the RH (Right Hand) rear window control switch or from the PDM (Passenger Door Module) through a private LIN (Local Interconnect Network). The PRDM (Passenger Rear Door Module) supplies voltage and ground to operate the RH (Right Hand) rear power window motor.
